Join us on November 7th, 2026, for the best endurance challenge in Southeast Florida! The Treasure Coast Endurance Challenge will take you through the stunning trails and waterways of Jonathan Dickinson State Park. Participants can choose between a 4-hour or 8-hour adventure race, and for those ultra runners, we will also be hosting a 25K and 50K ultra race (registration on ultrasignup.com), creating a dynamic mix of competitors and a fun endurance athlete atmosphere.
The 4-hour race is perfect for newcomers to adventure racing, families, or those looking for a shorter, more relaxed experience. In contrast, the 8-hour race offers a more competitive challenge, emphasizing navigation skills and endurance. Whether you’re a seasoned racer or new to the sport, this event promises an unforgettable adventure in a beautiful environment!
Race Distance: 12-24 Miles
Categories: Solo, Two-Person, Three-Person, and Four-Person Teams
Description: Teams of 1-4 will traverse land, water, and swamp in Jonathan Dickinson State Park, covering approximately 12-24 miles. Racers will use pre-plotted CalTopo maps to navigate to checkpoints while paddling, cycling, and trekking throughout the entire park. The checkpoints for the 4 Hour race will be more easily located than that of the 8 hour race as this is intended to be more beginner friendly. Checkpoints will be located at various natural landmarks, such as trail intersections, canals, bays, and wetlands, as detailed on the clue sheet. The race may feature single-track mountain biking trails, dirt or gravel roads, some paved roads, and flat-water kayaking/canoeing.
